A former congressional aide was indicted yesterday on charges of taking bribes to pressure government officials to make five Los Angeles vocational schools eligible for federal funds.

Named on the federal corruption charges was Stephen B. Elko, 49, who resigned last year as administrative aide to Rep. Daniel J. Flood (D-Pa.).

The indictment, returned by a federal grand jury in U.S. District Court in Los Angeles, charged the Falls Church, Va., man with conspiring to obtain bribes, conspiring to obstruct justice, lying to a federal grand jury, suborning perjury and causing interstate travel for the purposed of committing bribery.

Patricia Brislin, also of Falls Church, was indicted on the same charges.

William Fred Peters and Daryl Fleming were named as unindicted coconspirators. Peters was president of Aufomation Institute of Los Angeles, which owned six vocational schools. Fleming worked with Peters.

Five of the schools were not accredited, so they could not receive federal funds.

According to the indictment, Elko solicited "money, loans and other things of value" for himself and Brislin in exchange for using his position with Flood to pressure the U.S. Office of Education to accredit the five schools.

The schools were never accredited.

Flood chairs a House Appropriations subcommittee that has jurisdiction over education. The Justice Department said he was not involved.
